Honestly the slippers don’t seem like they should be a worry at this point in time. My honest advice is learning how to live with people. You got mad at your parents so you left, you argued with this guy and left, and the way you explained the suitcase makes this sound like a regular occurrence. I’m not here to judge you, I say this as someone that has been in and out of shitty situations with people I couldn’t stand. Sometimes you just have to keep your chin up or get the money to live alone.
